MACHINE FOR SHA P| SPECIFICATION forming part of Letters Application filed March 30, 1888.

To all whom it may concern:

' Be it known that I, EDWARD H. EVERETT, of Newark, Licking county, Ohio, have invented an Improved Machine 'for 'Shaping Bottle Necks, of which the following is a specification.

The object of my invention is to provide an improved machine for shaping bottle-necks.

The invention consists in a rotating spindle that has a plug or core at one end adapted to enter a bottle-neck, combined with rotating opening and closing shaping-jaws that are adapted to close upon the neck of a bottle and in their rotation around said bottleneck to give the desired shape thereto.

The invention also consists in means for opening and closing the shaping-jaws during rotation; also, in means for advancing the bottle, when a movable bottle-support is employed, in unison with the advance of the spindle.

The invention further consists in the details of improvement and the combinations of parts that are more fully hereinafter set forth.

- Reference is to be had to the accompanying drawings, forming part of this specification, in which Figure l is a side elevation, partly broken, of a machine for shaping bottle-necks constructed according to my invention. Fig. 2 is a plan view of the same. Fig. 3 is an-enlarged detail View, partly in section, showing thermechanism for opening and closing the shaping-jaws. Fig. 4: is a vertical cross-section on the line 0 c, Fig. 3. Fig. 5 is a vertical cross-section on the line 1070, Fig. 3. Fig. 6 is a side elevation, partly in section, of a modification of my machine, showing means for advancing the spindle; and Fig. 7 is a side elevation, partly broken, showing another modification of my machine adjusted sothat both the spindle and shaping-jaws may advance, also showing a modified arrangement for actuating the shaping-jaws.

In the accompanying drawings, the letter A represents a base or guide plate that is mounted upon suitable supports, a.

B is a spindle or shaft that isj ournaled in bearings 19 d, supported by the base A. The spindle B is rotated as follows: At one partsaid spindle is provided with a worm, e, that NG BOTTLE-NECKS.

Patent No. 400,555, datedApril 2, 1889.

BerialNo. 268,959. (No model.)

The shaft 1 is driven by belt and pulley from suitable source, or by other suitable means.

As the shaft t' rotates, the nut or sleeve ,D, through the connecting-rods f g and crank h, will be reciprocated without turning. As the sleeve D is thus reciprocated, its internal threads, working in the Worm 8, will rotate the spindle B alternately in opposite directions; but, if preferred, the spindle 13 could be rotated directly by belt and pulley or other suitable gear.

At the opposite end the spindle B carries a plug or core, E, that is adapted to enter the mouth of a bottle, At its inner end the plug or core E preferably has a plate or stop, Z, that limits the passage of the core into the bottle-neck. in a cup or snap, m; the handle or rod n of which is to be rested upon supports or bearings 0, that are carried by the guide-plate A. When a bottle j is placed in position upon the core E, the neck of the bottle is or may be passed through a ring or other shaped support or bearing, 13, that is supported on the base or guide plate A. When the bottle is in proper position upon the core E, the body portion of the bottle at the neck will fit in the ring-support 99, as shown in Fig. 3. The supports 0 0 and p are -preferably vertically adjustable. The ring-support 19 also acts to determine the distance the bottle-neck shall pass into the jaws F.

The base of-the bottle j is held F F are shaping-jaws that are adapted to v straddle the bottleneck and, also to rotate around said neck. The jaws F F aresupported by or are continuations of leversq, that are pivoted to arms r, that are carried by the spindle B. I prefer to secure the arms 0" to a sleeve, 8, that fits on the spindle B, as clearly shown in Fig. 3. I preferably secure the sleeve 8 to the spindle B by a set-screw, t.

G is a sleeve that fits over the sleeve .9 and slides freely thereon, being guided by a screw or pin, to, passing from the sleeve G tion I consider the parts G, 20, and as as one sleeve, which I term G.

To the sleeve G, or, more properly speaking, to the rods w, are pivoted links 3 that at their other ends are pivoted to the levers q. When the sleeve G is moved into the rearward position, or that shown in Figs. 1, 2, and 3, the links (1 act to press outward the outer ends of the levers q, and thereby crowd the jaws F toward the plug E and upon the bottle j when it is in position on said plug, or upon the plate 1, thereby limiting the movement of the sleeve G; but when the sleeve G is moved forward, or into the position shown in Figs. 6 and 7, the links y act to draw inward the ends of the levers q, and thereby to raise the aws F from the bottle-neck.

The sleeve Gmay be moved along the spindle B by aspring orby suitable means. I have shown two constructions for moving the same, one being shown in Figs. 1, 2, 3, and 6, and the other in Fig. 7.

Referring now to Figs. 1 to 6, the sleeve G is shown provided with an external worm, 2, that receives a pointer or finger, H, that is rigidly secured to the framing of the machine. This pointer H may be rigid or slightly yielding, as desired. As the sleeve G rotates alternately in opposite directions with the spindle B, said sleeve will be moved back and forth along the spindle by the action of the worm z and the pointer or finger H. Thus when the pointer H is in the end of the worm 2 (shown in Figs. 1, 2, and 3) the sleeve G will be in the backward position and the jaws F closed; but when the pointer H is at the other end of the worm, as shown in Fig. 6, the sleeve G will have been moved forward and the jaws F opened. The speed of the sleeve G along the spindle B, and also the distance it shall travel, can be regulated by the pitch of the worm, or otherwise.

My improved machine operates in shaping a bottle-neck as follows: The bottle 3', while in a plastic state and having a plastic glass ring, a (see Fig. 7,) in position on the neck of the bottle, is secured in the cup or snap m.

The bottle-neck is then passed through the support or ring 19 and upon the plug E while the jaws F are open, the handle 12. of the cup on being placed upon the supports 0 0. The spindle B is now rotated in such direction by the sleeve-D and its actuating-gear that the action of the worm z and the pointer H will move the sleeve G to close the jaws F upon the ring a and upon theneck of the bottle. As the jaws F in their rotation with the spindle approach the bottle-neck and ring a they act upon the same to shape the neck. The sleeve D is now moved in the opposite direction to reverse the motion of the spindle B. The worm z and pointer H now act to move the sleeve G forward to open the jaws and release the bottle-neck. As the plug E rotates within the bottle-neck, it acts to shape the interior of said neck. The length of time that the jaws shall bear upon the bottle-neck can be regulated by the shape of the worm e, or otherwise. Thus it will be seen that the jaws F close gradually upon the bottle-neck during rotation, andin so doing shape the neck, and then open as gradually to release the bottle; but the bottle-neck may be shaped by my machine without using a ring (1 For some styles of bottle-necks it is or may be necessary that the spindle should have a longitudinal movement as well as rotary, while the jaws F rotate without advancing. To accomplish this I provide the hearing (I for the spindle B with an internal worm, 12 that meshes with a worm, (1 on the spindle B, as clearly shown in Figs. 6 and 7. As the spindle rotates, it will be moved longitudinally by these worms. I prefer that the worm e be so cut with relation to the worms b d that as the sleeve D travels along the spindle B four inches the spindle will travel longitudinally one inch; but this relation of speeds may be changed to suit the requirements. The longitudinal movement thus imparted to the spindle B eases the friction between the worm c and the sleeve D. Vith this construction the sleeve .9 is held to the spindle by the screw If passing through the slot 1; in the sleeve 5. Thereby said spindle is permitted longitudinal movement Within the sleeve, while the pin t acts to turn the sleeve .9 with the spindle. To prevent longitudinal movement of the sleeve 8, and to permit its rotation with the spindle B, I provide the shoulder s with an annular groove, f that receives the ends of arms 9 that project from the bearing d. Thereby the sleeve 8 is free to rotate, but cannot move longitudinally; but the sleeve 5 may be otherwise swiveled so as to turn without advancing, if desired. As thus modified, the machine will act as before described, except that the plug E, while revolving within the neck of the bottle, is also moved longitudinally to produce a cylindrical opening in the neck.

If desired, the jaws F may be held so as not to rotate, ,while the plug E rotates and advances. The jaws may also be made to entirely clasp the bottle-neck, screw-threads or any desired device being produced on their inner faces. In this case the advancing of the plug into the bottle-neck would press the glass outward into the closed jaws, and thereby form the device on the bottle-neck that is on the inner face of the jaws.

In some cases as the spindle B advances it may also be desirable that the bottle-supports 0 0 p should advance and carry the bottle longitudinally, and that the jaws F should partake of such longitudinal motion. A This modification is shown in Fig. 7. In this figure the bearing-support b for the spindle B is made longitudinally movable and guided in a slot of the base A, a plate, h being carried by it below the base A, so as to hold and guide it on the base. To this sliding bearing b is also secured a rod, 4?, that passes along the base A, and is adj ustably secured to the supports 0 and p; which in this case are movable on' the base A. These supports, by means of setscrews, are longitudinally adjustable onthe rod 5 A collar, 3' on the spindle B, adjacent to the bearing 1), acts to push said bearing forward as the spindle advances, thereby imparting motion by the rod 2' to the supports 0 0 and p. In the return of the spindle B the sleeve 5, which in this case is rigid with'thespindle, acts to push the bearing 19 rearward to return the supports 0 0 and p with the spindle. I also prefer to secure to the bearing b a rod, Z that extends parallel with the spindle B, passes through the arm f, and is guided in a stationary support,m at the end of the base A. Upon the rod F, I place an adjustable collar, 01 that is adapted to be engaged by the arm f as it returns in driving the spindle, this collar thereby acting to limit the travel of the arm f.

In the construction shown in Fig. 7 the sleeve 8, as stated, is firmly secured to the spindle B by the screw it, so that the spindle and jaws will move lengthwise and rotate in unison, as first explained, the worms b d being also provided to impart'to the spindle and jaws F the longitudinal movement. The

means for rotating the spindle B are similar to those already described; but in this figure is shown a different arrangement for moving the sleeve G to open and close the jaws F F from that shown in the other figures. In this case the worm 2 on the sleeve G is replaced by an annular groove that receives a pin, 0 on a lever, I, that is pivotally connected to the bearing 1), as at 19 The lever I may be forked, if desired, to embrace the sleeve G, there being a pin, 0 for the groove at each end of the fork. The lever I extends downwardly and is attached by a chain, (1 or otherwise, to the arm f. The lever I is also connected by a chain or other flexible connection, W, with a weight, J said chain r passing over a pulley, t suitably supported by the framing of the machine. As the sleeve D advances in the direction of the arrow a, Fig; 7, to turn the spindle B, the support I) and its connections advance under'the influence of b d withone fourth the speed of f; hence the rear connection of .the chain q advances much faster than the pivot 19 of said lever, and the chain (1 will consequently slacken, allowing theweight J to swing said lever I on its pivot and to move the sleeve G backward and close the jaws F. As the sleeve D and arm f move in the reverse direction, the chain will draw upon thelever, I, thereby moving the upper end of said lever in the direction a to advance the sleeve G and open the jaws F. Thus it will be seen that the action of the weight J and arm f, through the medium of the lever I, serves to move the sleeve G to open and close the jaws F. The lever I', being pivoted to the movable bearing b, always retains the proper position with relation to the spindle B and sleeve G.

, By adjustingthe chain up or down on the lever I the distance the sleeve G shall travel may be regulated. By lowering the chain on the lever the pressure of the jaws on the bottle-neck may be increased.

The parts may be readily changed from non advancing spindle and jaws, Fig. 1, to advancing spindle. and non-advancing jaws, Fig. 6, and to advancing spindle, advancing jaws, and advancing bottle-supports, Fig. 7.

The worm z and pointer H may be used in connection with the advancing spindle and jaws (shown in Fig. 7) in place of the lever I and its connection.

With my improved machine both the inside and the outside of the bottle-neck are shaped at one time, and all strain by longitudinal or other action of the jaws on the bottle is avoided.

I have made a separate application for so much of the mechanism shown in Fig. 7 as covers theshaping-jaws, combined with means for revolving and opening and closing them, and a weighted member which will allow the jaws, when closed and in the act of closing, to yield; also, for the combination of the above with the spindle B, sleeve G, and weight J. Said application was filed in Patent Office November 9, 1888, Serial No. 290,370.
